Black Diamond Forearm Trainer

Description

The Forearm Trainer is an essential companion for warm-up or travel between session
A fixture on gear shifters for more than 20 years
Though Black Diamond's Forearm Trainer looks like a dog chew toy, it works surprisingly well at giving you a good forearm pump when you can't go climbing. Stash the Forearm Trainer in your desk at work or at home. Keep your arm strength up by squeezing it with each hand until you have good Coke bottle forearms, and you can barely type on your keyboard.
